Biological Safety Cabinet Internal Blower is not turning on

Hi Support,

I have a problem with my Biological Safety Cabinet.

The internal blower is not turning on. Everything is all installed and fine except that the damper actuator is missing from the installation list. Blower fuse is OK. Connections are OK.

What can be the cause.

Cytotoxic cabinet details; NUAIR, Model:NU-430-400E, Class II B2, LABGARD ES

Can anyone help me with some expert technical advice to solve my problem please.

Thanks

Equipment: Biological Safety Cabinet - NUAIR NU-430-400E
